I had not seen that yet JW, thanks for pointing it out.

OK... update.

I have replaced the temp sensor/oven probe with no change in oven behavior.I then replaced the control board/clock timer and while it seems a little better, I still see the following behavior:

Oven will preheat just fine to 350 and stay there just greatI put in a cookie sheet of cookies and temp stays at 350 for a few minutes... I look again in a few more minutes and it was up to 375-400 or so.So I opened the door a bit to bring it back down to 350. Sometimes it stays there for a while.

* I am using one of those metal-coil oven thermometers

Questions:- The thermometer is close to the cookie sheet... do you think that's an issue in giving a false reading? I will try it higher up in oven away from cookie sheet- Is there a way to clean out the venting system for this oven, or does that never have a problem? Could that contribute to problem?- Any other suggestions of what could be wrong?? I'm getting nervous with Thanksgiving coming up!

Thanks,Chris

I bought a second coil thermometer last night and it seems to be more accurate than first thermometer. Also, I guess temp can vary across the oven. I hung this thermometer right on the oven probe and it seemed to remain pretty accurate.

I will (hopefully) get some final results today as I test the oven again...
